In circulating fluidised beds, [[Biomass|biomass]] particles are introduced into a circulating bed of hot sand. The recirculated product gas, sand and [[Biomass|biomass]] move together in the reactor. The high heat transfer rates from the sand ensure rapid heating of the [[Biomass|biomass]] and ablation is more prevalent than bubbling fluidised beds. This reactor is characterised by good temperature control and high heating rates. The residence time for the tar produced is around the same for the vapour and gas and can be separated by cyclone. | |||
